TCST1210

Vishay Telefunken

Transmissive Optical Sensor with Phototransistor
Output

Description

This device has a compact construction where the
emitting-light sources and the detectors are located
face-to-face on the same optical axis. The operating
wavelength is 950 nm. The detector consists of a
phototransistor.
